Oscillation and nonoscillation for impulsive dynamic equations on certain time scales

open access: yesAdvances in Difference Equations, 2006
We discuss the existence of oscillatory and nonoscillatory solutions for first-order impulsive dynamic equations on time scales with certain restrictions on the points of impulse. We will rely on the nonlinear alternative of Leray-Schauder type combined

Neutral Difference System and its Nonoscillatory Solutions

open access: yesTatra Mountains Mathematical Publications, 2018
Abstract The paper deals with a system of four nonlinear difference equations where the first equation is of a neutral type. We study nonoscillatory solutions of the system and we present sufficient conditions for the system to have weak property B.

A classification scheme for nonoscillatory solutions of a higher order neutral difference equation

open access: yesAdvances in Difference Equations, 2006
Nonoscillatory solutions of a nonlinear neutral type higher order difference equations are classified by means of their asymptotic behaviors. By means of the Kranoselskii's fixed point theorem, existence criteria are then provided for justification of ...

Nonoscillatory solutions of systems of neutral differential equations

open access: yesHiroshima Mathematical Journal, 1992
The author considers the system of neutral differential equations of the form \[ (1\mu){d^ n\over dt^ n}[x_ i(t)+(-1)^ \mu a_ i(t)x_ i(h_ i(t))]=\sum^ N_{j=1}P_{ij}(t)f_{ij}(x_ j(g_{ij}(t))), \] \(i=1,2,\dots,N\), \(N\geq 2\), \(n\geq 1\), \(\mu\in\{0,1\}\), \(t_ 0\geq 0\), where (a) \(a_ i:[t_ 0,\infty)\to(0,\beta_ i ...
